Thanks for your review.

Maybe 'invalid' this words is not correct here, after i check the code 
in qemuRemoveSharedHostdev
there are some words in there:

"Currently the only conflicts we have to care about for the shared disk 
and shared host device is "sgio" setting, which is only valid for block 
disk and scsi host device."

I think this means we should do nothing for the network iscsi hostdev 
(just like what we do for the network disk, usb hostdev...). And i don't 
think it means the <shareable/> is invalid for these disk, because they 
are already 'shareable' in guests even libvirt do nothing.

But i cannot make sure i am right :)
